Well Arenanet is owned by Ncsoft for over 10 years now, so it actually is developed by Ncsoft, you could argue that Arenanet is somehow still an independent team but we all know thats just wishfull thinking , Ncsoft bought it and it belongs to them now they could just merge it into NcWest if they liked but they chose to let the team work under its Arenanet name because of brand recognition. Its the same EA did with Origin (they only use the name for their store system now lol) or Bioware or any dev studio that was ever bought by a publisher.

Thats what im trying to say its the same damn company, between aion and gw2 only the devteams are different management and support are the same so you cant say Arenanet i so mutch better and Ncsoft sucks and vice versa.
It just doesnt make sense.
